CAR-FENDER.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed August 28, 1911. Serial No. 646,318.

To all whom it may concern:

Be it known that I, NORMAN J. HOLDEN, residing at Montreal, in theProvince of Quebec, Dominion of Canada, have invented certain new anduseful Improvements in Car-Fenders, of which the following is aspecification.

My invention relates particularly to car fenders of the'typeembodyingmeans for applying the brakes in unison with the operation ofthe fender; and it has for its object to provide a fender of this typeadapt- 1 ed to cause the brakes to be applied, the power to be reversedand the sand projected upon the rails before the scoop fender reachesthe object struck.

The invention may be said to consist of the construction, combinationand particular arrangement of parts hereinafter described and pointedout in the claims.

For full comprehension, however, of my invention, reference must be hadto the accompanying drawings forming a part of this specification, inwhich similar reference characters indicate the same parts and wherein:

Figure l is a side elevation and part sectional view of the frontportion of a tram-car provided with a fender embodying my invention andready for action; Fig. 2 is a plan view thereof with the body of the carand platform removed; and Fig. 3 is a detail vertical sectional view ofone of the sand bins.

The body 5, platform 0, axle d, wheels 6, brake-shoes f, electric wiringfor power, and

an emergency air-brake system of which a portion only is illustrated at9, may be of any preferred construction and are not described in detail.

According to my invention, a scoop fender 2 located in close proximityto the front wheels, and a trip-fender 3 placed at the extreme front endof the platform, are employed in conjunction with the air-brake system,electric power and a pneumatic sander, and means are provided wherebywhen the trip fender comes into contact with an object upon the track,the brakes will be applied, power reversed and sand projected, beforethe fender reaches the object, thereby materially lessening the shockand facilitating the retention of the object by the scoop fender.

The trip fender consists of a horizontal bar 10 carried by a U-frame 12fulcrumed to a pair of bracket arms 14 fastened to the extreme front endof the, platform 0. The middle of this trip fender has an upwardlyextending and rearwardly curved rigid pawl 15 having laterallyprojecting pins 16 and 17 one, 16, of which has connected thereto aretractile. spring 18 the opposite end whereof is fastened rearwardly tothe underside of the platform. A locking disk 19, having a notch 20engageable by the pawl 15, is rotatably carried between the arms of aninverted U-bracket 21 secured upon the under side of the platform, andit is operatively connected to the scoop by a rigid link 22.

The scoop fender consists of an angular member pivotally supportedbetween the lower ends of a pair of depending bracket arms 30 located inclose. proximity to front wheels, the portion 31 thereof, which isnormally horizontal, being dished, and the vertical portion 32 isprovided with horizontal resilient strips 33 and a rigid vertical arm 34having the rigid link 22 pivotally connected to the lower portionthereof,and a retractile spring 35 has its ends connected to the upperend thereof, and forwardly to the under side of the platformrespectively, the upper. end of this arm being connected by a rod 40 toa combination lever 47 in operative relation with the power circuit,sander, and air brake mechanism.

Suitable wiring is provided for the reversal of the power upon themovement of a switch member. This wiring may consist of a series ofleads 90, 90 and 100, 100 conne'ctedto switch terminals 102, the leads90, 90 coming from the forward terminals of the controller box (notshown), and the leads 100, 100 from the reverse terminals thereof. Thebrake-pipe 104:, leading from the reservoir 105 to the brake cylinder106, has a by-pass 103. This by-pass is controlled by a three-way valve107, from the chamber of which a branch 108 leads to the pipe 110,furnishing a blast to a pneumatic sander 160, the stem of this valveprojecting through the casing and having an arm 114 with a contact piece115 carried thereby, and insulated therefrom. The relative positions ofthe valve 107, arm 114C, and switch terminals 102, are such that thevalve will be closed and the power directed for forward travel when thecombination lever 47 is in the position it is caused to assume when thefender is set ready for action; and the throw of the lever and thecontact arm is such that the current will be reversed and the valveadmit air to the brake cylinder and to the sander simultaneously withthe touching of an object by the tripfender.

The sander illustrated consists of the usual bin 150 located in themotor-mans cab. It has a hopper-bottom 151 from which a branchedconductor pipe 152 leads to a point in close proximity to the rails andthe front of the front wheels. The mouth of this pipe is covered, withinthe bin by an agitator chamber 160 having slots 112 and with which abranched pipe 161 connects, the compressed air pipe 104. being coupledby a pipe 110 to this branched pipe 161. Agitation of the sand in thechamber is caused by the impact of the air on the walls of the cavity inthe mass of sand and surrounding the chamber, and the whirling effectdue to the circular form of the latter. In this manner the speed of thecar is materially checked, if not brought to an absolute stop, betweenthe time the trip fender touches an object and the scoop fender reachesit, with the result that injury to the object is prevented, and it isprevented from rolling oif the scoop fender and being ridden overthereby and cut up by the wheel.

In order to enable the motor-man to ap ply the brakes and simultaneouslydrop the fender on an emergency, and readily restore the air-brakesystem, power system, sander, and fender to normal condition, a footlever 50 is fulcrumed to the lower end of a bracket arm 51 extendingbelow the level of the pin 17 of the locking pawl and is secured to theunder side of the car platform, such lever projecting upwardly a shortdistance through a slot in the platform and being located in a positionto have this pin 17 eX- tend across it; and a plunger bar 60 with a footpiece 61 on its upper end extends of the bar 60 in a substantiallyhorizontal line with the center of the disk when the brakes are applied.

WVhat I claim is as follows 2- 1. In a car the combination with atripfender, an air-brake system, a pneumatic sander and electric powersystem, of means whereby the said brake system and sander are operatedand the power reversed simultaneously with the movement of thetripfender.

2. In a tram-car the combination with an air -brake system, a sander,and electric power system, of a displaceable member suspended from theunderside of the extreme front of the car, a scoop-fender carriedbeneath the car body and in close proximity to and in front of the frontwheels, and means whereby upon displacement of the displaceable memberthe air-brake and the sander will be operated and the power reversedbefore the scoop-fender reaches the point at which the said member wasdisplaced, substantially as described.

3. In an electric tram-car having an airbrake system the combinationwith a tripfender, of a combination lever mounted on the car, meansoperatively connecting the fender to the lever, a valve controlling theair-brake system, a device carried by the movable part of the valve, andadapted to control the electric power, and means operatively connectingthe lever to the valve.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
